HENRY LoBDnLL, or TROY, NEW YORK.

SPEGIFICATION formingpart of Letters Patent No. 282,541, dated August'7, 1883.

To all whom) it may concern K Be it known that I, HENRY LOBDELL, aresident of the city of Troy, in the county of Reusselaer and State ofNew York, have invented certain new and useful Improvements in VVall-Paper; and I do hereby declare that the following is a full, clear, andexact description of the invention, that will enable others skilled inthe art to which it appertains to make and use the same. i n

My invention relates to improvements in wall-paper hangings anddecorations; and it consists in manufacturing or preparing wallpaperwith a dry sizing or adhesive substance on its unprinted surface readyfor use, thereby producing a new article of manufacture.

The objects of my invention are'hereinafter fully set forth.

Heretofore it has been the practice in manufacturing or preparingwall-paper for the market to leave the back side of the paper blank,rendering it necessary for the paperhanger to prepare the paper for useat the place where it was to be used by applying wet paste or sizing toits blank surface. The wet paper was then hung upon the wall, to whichthe My method is to manufacture or prepare the paper ready for use witha dry sizing on the unprinted surface of the paper. Any of thewell-known methods of dry sizing may be employed.

In the use of wall-paper manufactured as last above described it is onlynecessary for the hanger to moisten the sized surface and apply it tothe Wall.

The paper and paste are thus manufactured or prepared and supplied tothe trade as a single, new, and easily-distinguished article ofmanufacture, ready for use without the in- .tervention of any othermanufactured ingredient;

By applying the sizing to the paper in its manufacture or preparationfor the market at the factory, instead of by the hanger at the placewhere it is used, a more uniform distribution of the sizing upon thesurface of the paper is secured, which gives the paper a smoother andmore finished appearance upon As it is only necessary to moisten thewall.

Application filed July 7, 1883. (No specimens.)

I the dry sizing to cause it to adhere to the wall, and not to saturatethe paper, as was the case with all wall-papers heretofore manufac'tured, the paper does not expand or'stretch before being applied to thewall and shrink again when dry,-as heretofore. As the expansion andshrinkage varied in different parts of the paper, it caused the figuresand designs on the printed surface of the paper to mismatch on the edgesof the adjoining rolls of paper.

In all papers heretofore manufactured the uneven drying and shrinking ofthe paper 011 calcimined walls would pull off the calcimine inplaces andloosen the paper: "When the.

paper is manufactured and prepared as I have described, it is not wetsufficiently in hanging to discolor its pginted surface after dryingagain, as is the case with all papers heretofore manufactured.

My paper can be hung upon a wall or ceiling much more conveniently andquickly than paper manufactured in any other way, and

the cost is notgreater than the combined cost I of unsized paper and thepaste or wet sizing heretofore used.

I am able to use much thinner and cheaper paper in the manufacture of mydry-sized wallpaper, for the reason that it isnot weakened in hanging bybeing saturated with moisture.

It is well known to those skilled in the art that the thinner the paperthe better the re sults in hanging, provided only the paper hassufficient strength to resist tearing. It is equally well known thatwall-paper manufactured in the usual manner with dull or soft sizing onthe printed surface cannot be hung without disturbing-or changing itscolored surface or print, and that the figures of embossed wall-paperareinjured in hanging; but when the paper is manufactured or preparedwith the dry sizing, as I have described, the color and figures arefully preserved.

In hanging my dry-sized wallpaper the edges of the paper rolls or stripscan be successfully butted edge to edge without leaving open seams,caused in other papers by expan sion and shrinkage, and the edges of therolls can be pressed down closely upon the wall In testimony whereof1.11m hereunto set 10 Letters Patent, is-

without danger of forcing the paste out upon my hand this 5th day ofJuly, 1883.
